Type material.

Holotype: male, specimen PNG2008-0360 in UBC–SEM, with data PAPUA NEW GUINEA: Enga Province: Kai-ingri. 5.579 S 143.053 E. 3240 m a.s.l. 7-9 July 2008. W Maddison & Manisé Kulé leg. WPM#08-005. Beating understory of Phyllocladus forest. Paratype: female, specimen PNG2008-0370, with same data as holotype, in UBC–SEM.

Etymology.

Named in honour of Dr Herbert W Levi.

Diagnosis.

Body somewhat smaller, less elongate, than the other species of Leviea , and with fewer (3 or 3.5 pairs) ventral macrosetae on first tibia. The robust dorsal branch of the RTA ends bluntly like a thumb, unlike the tapering and dorsally pointing tip of the other species. Bulb ca. 90° further rotated than in L. lornae and L. francesae , as indicated by the spermophores (Figs 5, 21, 38).

Description.

Male (holotype). Carapace length 1.82; abdomen length 1.96. Carapace (Figs 12, 14, 15): Of typical salticid shape, without constrictions or thoracic hump. Chelicera (Fig. 13): Vertical, simple except for a small ectal spur on the paturon. At least five retromarginal teeth. Palp (Figs 5, 6). With round bulb. Embolus circling 1.8 times around, ending in broad tip. RTA appearing as a finger and thumb (dorsal apophysis and ventral flange, respectively), with the dorsal apophysis pointing somewhat ventrally. Legs unremarkable, first somewhat more robust. First tibia with three pairs of ventral macrosetae, of normal length (right tibia bears an extra small distal anterior macroseta). Colour in life (Figs 9-12): Markings are muted beige to reddish brown, with the digestive diverticula in the ocular area providing two pale stripes that continue as pale areas on the thorax and chevrons on the abdomen. Colour in alcohol (Fig. 13-15): Body and appendages honey coloured, with indistinct dark annuli on the legs, and chevrons on the abdomen. Underside of abdomen with two longitudinal dark stripes.

Female (paratype, specimen PNG2008-0370). Carapace length 1.89; abdomen length 2.16. Carapace, legs, abdomen substantially as in male (Figs 16-18, 20), except for the less robust first legs. First leg tibia with seven ventral macrosetae (three pairs plus one prolateral-distal) (Fig. 19). Epigyne (Figs 7, 8): Of fairly typical myrmarachnine form. RTA pocket more distinct and larger than in L. lornae . Colour (Figs 16-18, 20): As in male, but with body and chelicerae darker, and palps bright yellow in life.
